What is A360-F?
A360-F is A360 in the F temper — standard supply condition for A360 die castings — use for thin-wall pressure-tight housings needing strength above ADC12. A360-F has a yield strength of 165 MPa (23.9 ksi) and a tensile strength of 317 MPa (46 ksi) — weaker than 59% of aluminum grades. Elongation at break is 3.5% and the elastic modulus is 71 GPa (10.3 Msi). A360-F has a density of 2.63 g/cm³ (0.095 lb/in³), lighter than 95% of aluminum grades. It melts at 557°C (1,035 °F).
Limitations
- Poor heat conductor — 113 W/m·K (65.3 BTU/hr·ft·°F), worse than 86% of aluminum grades
- Limited formability — 10/100, worse than 81% of aluminum grades
- Low electrical conductivity — 29 % IACS, worse than 78% of aluminum grades
- Limited ductility — 3.5%, worse than 76% of aluminum grades

Working with A360-F
Is A360 easy to machine?
Machines freely with sharp positive-rake tools and flood coolant, but 9–10 % Si is abrasive — use PCD or polished carbide and expect built-up edge with soft alloy chips.
Can A360 be welded?
TIG/MIG with 4043 or 4047 filler works on printed or low-porosity parts; high-pressure die castings often blister or crack from trapped gas, so favour mechanical joining or adhesive.
Can A360 be formed, bent or molded?
Excellent die-casting fluidity and hot-tear resistance for 1–3 mm walls; keep die temperature and vacuum control tight to limit porosity, and avoid post-cast solution treatment on HPDC parts.
What surface finishes work on A360?
Takes chromate/chrome-free conversion coatings, powder coat and paint well; anodizing gives a dark grey film, so use hardcoat only where wear matters and shot-blast or vibratory finish for cosmetics.

A360-F — frequently asked
What is A360-F used for?
A360-F is typically used for cellphone and electronics housings, cookware, L-PBF printed brackets and manifolds, pressure-tight pump and valve housings, automotive covers and brackets and lighting and heat-sink bodies. In short: pressure die cast Al-Si-Mg.
What is the yield strength of A360-F?
A360-F has a typical yield strength of 165 MPa (23.9 ksi) and a tensile strength of 317 MPa (46 ksi) — weaker than 59% of aluminum grades. Strength varies by condition: see the 4 listed tempers.
Is A360-F easy to machine?
Reasonably — machinability is rated good (55/100, worse than 58% of aluminum grades). Machines freely with sharp positive-rake tools and flood coolant, but 9–10 % Si is abrasive — use PCD or polished carbide and expect built-up edge with soft alloy chips.
Can A360-F be welded?
With care — weldability is rated fair (40/100). TIG/MIG with 4043 or 4047 filler works on printed or low-porosity parts; high-pressure die castings often blister or crack from trapped gas, so favour mechanical joining or adhesive.
What surface finishes work on A360-F?
Takes chromate/chrome-free conversion coatings, powder coat and paint well; anodizing gives a dark grey film, so use hardcoat only where wear matters and shot-blast or vibratory finish for cosmetics.
Can A360-F be formed, bent or molded?
Excellent die-casting fluidity and hot-tear resistance for 1–3 mm walls; keep die temperature and vacuum control tight to limit porosity, and avoid post-cast solution treatment on HPDC parts.
What is the maximum service temperature of A360-F?
A360-F is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
